LM2596TV-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596TV-5.0 is a monolithic integrated circuit step-down switching regulator manufactured by TAEJIN Technology Co., belonging to the LM2596 series. It provides a fixed 5.0V output and supports a maximum load current of 3.0A with excellent line and load regulation. The device operates at a fixed internal oscillator frequency of 150kHz, enabling the use of smaller filter components compared to lower-frequency regulators. It accepts a wide input voltage range and requires only four external components for operation. The component utilizes TO-220-5 through-hole packaging.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the manufacturer designation corresponds to TAEJIN Technology Co. rather than Texas Instruments or other licensees. Confirm the suffix 'TV' indicates the specific TO-220-5 through-hole package variant. Ensure compliance with required environmental standards such as RoHS if applicable to the specific production batch.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output is required from a higher input voltage source up to 40V. The 150kHz switching frequency allows for compact passive component selection. Consider the TO-220-5 package for through-hole assembly requirements where surface mount options are unsuitable. Ensure the application demands a continuous 3.0A output capability.

Voltage Regulators - DC DC Switching Regulators Part Context

This component is part of the LM2596 family of buck converters originally developed by National Semiconductor and now produced by various manufacturers including TAEJIN. The series is widely recognized for simplifying switch-mode power supply design due to its minimal external component count and robust protection features. The TV suffix typically denotes the through-hole TO-220-5 physical package configuration.
